cannot see jupyter nbextension configurator tab

[yunqu]

I am able to use the URL to access the configurator tab (meaning that everything is installed properly?), but I cannot see the configurator tab in my jupyter:

# pip3 freeze | grep jupyter
jupyter-client==5.2.3
jupyter-console==5.2.0
jupyter-contrib-core==0.3.3
jupyter-contrib-nbextensions==0.5.0
jupyter-core==4.4.0
jupyter-highlight-selected-word==0.2.0
jupyter-latex-envs==1.4.4
jupyter-nbextensions-configurator==0.4.0

I have tried reinstall jupyter nbextension as well as the configurator again, but still not working. Any idea?

[xappppp]

Same here

[zhiruiwang]

My configurator tab also disappeared recently, but after re-executing

jupyter nbextensions_configurator enable --user

it will show up again.

[yunqu]

@zhiruiwang Tried that but no change. Still missing.

[Liluoai]

I have the same problem.

[kraeml]

Same here. I also tried @zhiruiwang but no change.

pip3 freeze | grep jupyter
jupyter==1.0.0
jupyter-client==5.2.3
jupyter-console==5.2.0
jupyter-contrib-core==0.3.3
jupyter-contrib-nbextensions==0.5.0
jupyter-core==4.4.0
jupyter-highlight-selected-word==0.2.0
jupyter-latex-envs==1.4.4
jupyter-nbextensions-configurator==0.4.0

On an other jupyter installation the nbextensions is running.

Here the output pip3 freeze:

jupyter==1.0.0
jupyter-client==5.2.3
jupyter-console==5.2.0
jupyter-contrib-core==0.3.3
jupyter-contrib-nbextensions==0.5.0
jupyter-core==4.4.0
jupyter-highlight-selected-word==0.2.0
jupyter-latex-envs==1.4.4
jupyter-nbextensions-configurator==0.4.0

I wondering jupyter-notebook version was not printed:

Here on not working:

jupyter-notebook --version
5.7.0

With working extensions:

jupyter-notebook --version
5.6.0

[mmcguffi]

Same here with 5.7.0 -- previously I had this working on a different system, which (presumably) had an older version of jupyter

@kraeml
I found that jupyter-notebook version is printed as below.

$ pip3 freeze | grep notebook
notebook==5.7.0

In GitHub repository, jupyter-notebook installation is described below.
https://github.com/jupyter/notebook

$ pip install notebook

So, I downgrade jupyter-notebook version from 5.7.0 to 5.6.0.

$ pip3 uninstall notebook
($ sudo chown -R $USER:$USER ~/.local    #  if permission error, you need to run this command)
$ pip3 install notebook==5.6.0

but if you pip install some PyPI package, it may automatically upgrade jupyter-notebook version to 5.7.0.
Then, uninstall 5.7.0 and install 5.6.0 again after installing some PyPI package.

Work by these in my environment.

[jupyter-notebook 5.7.0]
You might know you can access to the nbextension configurator from a notebook with a click.

[mazzma12]

the tab is still missing on jupyter-notebook 5.7.0 but you can indeed access the configurator via the URL directly : http://localhost:8888/nbextensions

+1 on this issue. same thing. it is accessible via the dropdown and url but the tab is missing in notebook version 5.7

[Idodox]

+1, same issue. Can access via the direct URL, but can't see the tab on the home page. Also on 5.7.0

[jupyter-notebook 5.6.0]

This is what happened when I opened http://localhost:8888/nbextensions

I have the same issue: 404 : Not Found

The missing configurator tab is due to a left over jqueryui reference.
